Answer:
x = 2.37
Explanation:
ln x = 0.863
apply e to both sides of the equation:
e^(ln x) = e^0.863
e^(ln x) = x = e^0.863
{Demonstration of e^(ln x) = x:
y = e^(ln x)
apply ln to both sides of the equation:
ln y = ln (e^(ln x))
apply logarithmic property (ln xⁿ = n ln x)
ln y = ln x * ln e (ln e = 1)
ln y = ln x
Then:
y = x
Because y = e^(ln x) and x = y, then:
x = e^(ln x)
End of the demonstration }
Returning to our equation:
e^(ln x) = e^0.863
Then,
x = e^0.863 = 2.37

Answer:
A leaf needs carbon dioxide and water for photosynthesis. ... For carbon dioxide to enter, the stomata on the surface of the leaf must be open. As you have seen, transpiration draws water from the roots into the leaf mesophyll.
I hope this helps you :)
<span>Answer:
CuX = Cu2+ + X2-
Ksp = [Cu2+] * [X2-]
for each mole of CuX that dissolves we get x mol of each of the anions and cations
Ksp = x^2 = 1.27 x 10 ^-36
x= 1.13 x 10 ^-18 moles of CuX per liter of pure water
if the solution has [Cu2+]= 0.27 M
Ksp becomes x ( x + 0.27)
as we can see above x is extremely small so can be ignored inside the brackets
0.27 x = 1.27 x 10^-36
x = 1.27 x 10^-36 / 0.27 = 4.70 x 10 ^-36 moles per liter
In 0.19M X2- we have
Ksp = 0.19x = 1.27 x 10^-36
x = 1.27 x 10^-36 / 0.19 = 6.68 x 10 ^-36 moles per liter</span>
